Slight problem with this...the Indigo tribe takes criminals and forces them to feel compassion. Other then that hiccup, a very interesting concept since Generosity is very really affiliated with Compassion.

"I was chosen to the prime lantern when I protected Diamond Tiara. Scootaloo was about to murder Diamond Tiara, and well, I know the horrible things she's done to Sweetie Belle and her little friends but . . . no foal deserves what Scootaloo did to her, I also used my favorite scarf to stem the bleeding."

Prince Blueblood "Auntie! This is simply unacceptable! I gave her the honor of being my escort for the evening and the honor of protecting me from a dangerous giant cake, and she did nothing but dirty and humiliate me! I demand to be given the same power as the mare who was rude to me at the gala!"

IH Rarity: "To be generous is to know what the others want; and to know what the others want, one must know their feelings; to know their feelings, one must know compassion. Both are interlinked, both walk side by side, both work together as one. And with both in my heart, I walk the path of the Indigo."

IH Rarity, "Now then, Flim and Flam, Evil Military Canterlot Cabal, and that mare who was extremely rude to Fluttershy just before the whole New Fluttershy mess, we're going to have a nice chat with prince Blueblood, Gilda is sadly beyond my reach and Trixie I can not find at the moment. But I'm certain the prince could use an improvement in personality."

Hmm♪ I have an interesting bit of trivia for you: In the Japanese dub they actually ended up adjusting a bit of the dialogue in the second episode, as a result in the Japanese version you can translate Rarity's element as "Compassion"

Do you think Diamond Tiara and Silver Spoon would be killed and turned into Orange Lantern by Spike first, or would Rarity force recruit them, and the FlimFlam brothers and Prince Blueblood into the Indigo Tribe?
